These are water filter replacement cartridges for our Moby TBC. The Moby TBC is a two stage mains water filter that improves taste and odour, removes chlorine, chemicals and sediment and filters out bacteria and other micro-organisms.
You will get:
or on some occasions a Pure CTO 4510-05 cartridge may be sent. This does the same job as the Watts WCBFF975. They're just different brands.
We send out an email every 6 months to remind you to check your filter performance.
You can tell if the seals start leaking, which is obvious, I know.
Even if there are no leaks you may find that the profile of the O ring becomes flattened because of prolonged time under compression. The cross section should be round and if it's not it may not seal easily.
However, I recommend that you replace the O rings every two or three years as a precautionary measure.
One of the main reasons for changing O rings periodically is that as they age and compress, the housing bowl needs to be tightened excessively. That leads to difficulty loosening the bowl from the cap next time the cartridge needs to be replaced.
